    <P align="left"><I>Undo</I> is a generalized capability for returning a program back to a state
    prior to the last edit operation.&nbsp; <I>Redo</I> is the opposite of <I>Undo</I> and it
    effectively re-applies the last edit operation.&nbsp; <I>Undo</I> can be applied repeatedly to
    erase the effects of&nbsp; a sequence of edit operations up to a current limit of 20.&nbsp;
    After performing a sequence of <I>Undo</I> operations, the same number of <I>Redo</I>
    operations are available. However, the instant a new edit is performed, the <I>Redo</I> list is
    cleared.&nbsp;</P>

    <UL>
      <LI>To <I>undo</I> an edit operation, select <B>Edit<IMG src=
      "help/shared/arrow.gif">Undo</B> from the main menu or press the <IMG src="icon.undo">
      button on the tool bar.</LI>

      <LI>To <I>redo</I> an edit operation, select <B>Edit<IMG src=
      "help/shared/arrow.gif">Redo</B> from the main menu or press the <IMG src="icon.redo">
      button on the tool bar.</LI>
    </UL>

    <P><IMG src="help/shared/tip.png"> Hovering the mouse over the <IMG src="icon.undo">
    button will display the name of the edit operation that would be "undone".&nbsp; Similarly,
    hovering the mouse over the <IMG src="icon.redo">button will display the name of the edit
    operation that would be "redone".</P>

    <P><IMG src="help/shared/tip.png"> Also, pressing the drop-down arrow will show a list
    of all the undo/redo's that are available. Clicking on one of those will undo/redo that
    item and all the ones above it.</P>
